What It Does:

The 66RR O-Ring provides sealing at the nozzle holding nut and sandblast tip assembly. A properly sealing O-ring helps maintain the integrity of the nozzle connection during operation.

Sandblasting equipment operates in an extremely abrasive environment, and O-rings can deteriorate from age, compression, repeated nozzle changes, and exposure to abrasive dust.

Because it is a wear item, the 66RR O-ring should be inspected whenever the nozzle or holding nut is removed. A damaged or hardened O-ring should be replaced before the equipment is returned to service.

Common Reasons for Replacement:

• O-ring is cut, nicked, or torn
• Rubber has become hard or brittle
• O-ring is flattened or permanently compressed
• Leakage around the nozzle holding nut
• O-ring was damaged during nozzle removal
• Original O-ring is missing
• Servicing or rebuilding the nozzle assembly

Finding Parts for Older PK Lindsay Equipment

PK Lindsay abrasive blasting equipment may no longer be manufactured, but many of these machines remain in service. Small components such as nozzle seals, O-rings, holding nuts, and related hardware can be especially difficult to identify when working from older exploded parts diagrams.

That's why we include the original PK Lindsay part number and exploded diagram item number whenever possible—so you can identify exactly what you need before ordering.

Important:

This listing is for the PK Lindsay 66RR Nozzle Holding Nut O-Ring – Diagram Item #12 only.

The nozzle, nozzle holding nut, and other components shown in the exploded parts diagram are sold separately unless specifically stated otherwise.

Always depressurize the blast machine and verify that all pressure has been released before servicing the nozzle or any other component of the blasting system.
